The fundamental contributions of Professor Maz'ya to the theory of function spaces and especially Sobolev spaces are well known and often play a key role in the study of different aspects of the theory, which is demonstrated, in particular, by presented new results and reviews from world-recognized specialists. Sobolev type spaces, extensions, capacities, Sobolev inequalities, pseudo-Poincare inequalities, optimal Hardy-Sobolev-Maz'ya inequalities, Maz'ya's isocapacitary inequalities in a measure-metric space setting and many other actual topics are discussed.

'A vocal performance that stops you dead in your tracks' (FATEA Magazine) Maz O'Connor is a gifted singer of traditional and self-penned songs. In 2013 she was nominated for the BBC Folk Awards Horizon Award and selected for a creative fellowship with the English Folk Dance and Song Society at London's Cecil Sharp House, funded by the BBC Performing Arts Fund. She sings both traditional folk songs and her own compositions, and accompanies her uniquely pure voice with guitar, shruti box (an idea she "nicked" off fellow folk artist Karine Polwart), piano and harmonium. Maz has been singing on the UK folk scene since she was 13 years old.
